Continuity mistake: In the scene on the plane at the beginning, just before the bomber speaks, a stewardess passes in front of the camera. It's obviously to cover a cut - after she's passed, the amount of sun visible on the seats changes, the two women behind are closer to the camera, and the nun's looking the other way. (00:02:15)
Continuity mistake: In the start of the film Lucy Liu is jumping out of a helicopter with a black parachute rig on her back. In the next shot we see her tracking towards Drew Barrymore, notice the deployment system (BOC) in the bottom of her rig (blue plastic handle). In the next scene we are watching her from from the front and you can now see the deployment system has changed both colour to red and it is now "pull out" instead of BOC. (00:03:30)
Continuity mistake: At the beginning when the guy with the bomb and Drew Barrymore's character, in disguise, are falling out of the plane the guy with the bomb has it still strapped to his chest but after they land in the boat the vest has disappeared. It reappears a few moments later but then again disappears. (00:04:10)
Continuity mistake: At the start of the film just as Drew Barrymore in disguise drops down into the boat you see her disconnect her parachute from the straps around her body. However in the next shot you can see that the straps are gone. She never had time to remove them. (00:04:50)
Continuity mistake: In the scene where Drew Barrymore takes off her LL Cool J mask, you can see he had dark brown eyes before she takes the mask off. After she takes off the mask and flips her hair, her eyes are green. She obviously would have had to have worn dark brown contact lenses with the disguise, but there's no shot of her removing them. (00:05:00)
Continuity mistake: Drew's car is parked at an angle when she looks back at Chad before jumping in the car, but then when skidding out she's straight as an arrow. (00:08:05)
Continuity mistake: In the scene where the Angel throws Lucy's "homemade" muffin: The first muffin actually broke through the door and you could see the depth and the cracks around the point of entry. When the girl comes through the same door, you can see the door no longer has a hole in it, just a fake muffin with adhesive attached to the door to look as if it had done so previously. (00:11:30)
Continuity mistake: When Cameron Diaz throws the muffin at the door, it is sitting up normally and in the door fully. However, when Bill Murray enters, the muffin is only half way in and on an angle. (00:12:00)
Continuity mistake: The picture of the "Creepy Thin Man" changes from the original one to the one Cameron Diaz later holds in her hand. (00:17:10)
Continuity mistake: In the party scene, when Bosley is talking to the president of Red star he is offered blowfish (1 in sixty chance of death etc.) when the dish is first brought out there is nothing on it - but when Bosley takes one he pulls saran wrap off of the dish. (00:19:25)
Continuity mistake: In the party scene, Tim Curry and Bill Murray are talking and a waitress comes up to them. In the first shot she is in front of them both and in the next she is suddenly behind Tim. (00:19:25)
Continuity mistake: In the scene where Alex spots the Thin Man for the first time, we see Dylan wearing opened toe heels. As soon as they are in the stairwell, they seem to become boots. I don't know about you but I can't change my shoes while running. (00:22:52)
Continuity mistake: In the first pursuit of the Creepy Thin Man, at the party, the girls are running down the stairs while they change and begin to litter the stairwell with clothes. There's one wig dropped that's dark brown/black and straight. Though Lucy's hair at the party does appear shorter than her actual hair length, her hair is curled up at the ends, not straight like the dropped wig. So whose was it? (00:23:05)
Continuity mistake: In the fight with the thin man, after Natalie hits him Dylan already has her leg lifted to hit him but Alex doesn't. In the next shot they lift and hit at the same time. (00:25:20)
Continuity mistake: In the scene where the girls are fighting the Creepy Thin Man, there is one shot where Dylan and Alex are about to kick him in the chest together. They start the kick both standing on their left legs and kicking with their rights, but when the kick connects to The Creepy Thin Man's chest, Alex is now standing on her right leg and kicking with her left. (00:25:27)
Continuity mistake: When the girls are at the race track, in one shot you can see Lucy Liu flashing a bit of cleavage (when she's wearing headphones). Then shortly afterwards she's behind Corwin's car, and she's got a relatively high collared black T-shirt on. (00:29:05)
Continuity mistake: At the race track, when Dylan jumps into the chauffeur's car, she says, "It's hot out there". A couple of scenes later, we see Creepy Thin Man rubbing a piece of Dylan's hair on his face, and breathing heavily. Look closely, and you can see fog coming out of his mouth. As we all know, that only happens when it's cold. (00:29:55 - 00:31:35)
Continuity mistake: When Cameron Diaz is racing down with F-1, one of the cars flips and crashes. Notice that it's very obvious there's no-one in any of the cars, even though they're supposedly driving along the street, at traffic lights, etc. (00:31:50)
Continuity mistake: In the racing car sequence Natalie chases Creepy Thin Man. As they approach the bridge the sky's completely overcast, but when they're facing each other on it, it's suddenly clear blue sky. Then in different shots the sky changes. (00:32:00)
Continuity mistake: After the two cars hit each other, and Crispin Glover's car is catapulted over the bridge, as his car falls, take a close look - there's no damage at all. Even though he skipped over Cameron Diaz's car rather than ploughed right into it, you'd expect there to be some indication... (00:32:30)
Suggested correction: Knox wasn't a trained pilot. Either he had no clue to what was going on, or he thought something may have been wrong, but didn't know what to do about it.
Taking off and landing a helicopter are by far the most intense and difficult part of a pilot's training. Seriously, 99% of learning to fly is learning how to land and take off. If the pilot is skilled enough to take off in a Huey he is easily skilled enough to notice a massive additional drag on his helicopter due to the additional weight of the angels and the air resistance put up by such a bulky protrusion on his aircraft. If he isn't skilled enough to notice that, he isn't skilled enough to take off in the first place.
